How to use it

! The watermark is burned into the pixels — the original file is not modified.
! Photos of poor quality may not be readable after a dense watermark; increase font size or lower opacity.

Why should I watermark a copy of my ID?

A dated, purpose-bound watermark makes the copy useless for a different application, which is the main protection against identity reuse.

Is the watermark removable?

It is blended into the image pixels, so removing it would visibly damage the document.

Do you store my document?

No. There is no server that receives the file.

Processing happens in your browser using the File API, WebAssembly and Web Workers. There is no upload endpoint.
